True Believers in Food Addiction

The popular notion that obesity is caused by some sort of food addiction has a surprising number of true believers. Scientists can’t keep up with public enthusiasm for the concept. Though close to 75% of the public believes that food addiction causes obesity, scientists are having a hard time coming up with a definition of food addiction that holds up to objective scrutiny. No matter. Many people — perhaps as many as half the population — believe themselves to be addicted to some foods.

And then there’s the possibility that thinking of oneself as addicted to food might help some people find their way to healthier eating behaviors. Helen Ruddock and colleagues examined this possibility with two studies published in Obesity. They found that a totally bogus suggestion that people might have food addiction tendencies had the effect of leading them to be more careful about what they eat.

Ruddock et al only measured the acute effect of this food addiction finger wagging. Perhaps the effect will fade in longer-term studies. What’s unlikely to fade is the righteous fervor of true believers in food addiction. Every crusade needs an enemy to rally against. Addictive, highly processed foods are serving that purpose quite well.
